Advanced Applications of Digital Mammography: Tomosynthesis and Contrast-enhanced Digital Mammography
John Lewin, M.D., FACR

Clinical studies of digital mammography versus screen-film mammography showed limited benefits in performance for digital over screen-film leading many to conclude that the true benefit of digital mammography would be in the advanced applications made possible by that technology. Now two of those applications, digital breast tomosynthesis (DBT) and contrast-enhanced digital mammography (CEDM), have advanced to the stage of clinical use. Both technologies show clear performance advantages over standard mammography but both have their limitations in terms of cost and, in the case of CEDM, the need to inject IV contrast. This talk will review the both DBT and CEDM, including the technology, clinical evidence, current clinical status and recent technological developments.

What Medical Physicists Need to Know about Breast Imaging with Nuclear Medicine Technology
Carrie Hruska, PhD

The use of dedicated nuclear medicine technologies for breast imaging, such as molecular breast imaging (MBI), breast specific gamma imaging (BSGI), positron emission mammography (PEM), and dedicated breast PET, is growing and may be coming to your site. Will you be ready?

Although these technologies have been under study for over a decade, concerns about radiation dose and unclear clinical indications for their use have limited widespread acceptance. Today, improved detector technology and modified imaging protocols permit imaging at reduced radiation doses. A growing body of clinical data supports their use as a functional complement to mammography and a low-cost alternative to MRI in certain diagnostic and screening settings.

Learning Objectives:
1. Give participants an overview of the various nuclear medicine technologies for breast imaging.
2. Demonstrate how each technology is being used in clinical practice and research.
3. Enable participants to discuss radiation doses used in breast imaging and their associated risk.
